You should use it as
你应该把它用作
return view('posts.index')->with(compact('posts'));

You'd better use withlike this:
你最好这样使用with：
return view('posts.index')->with('posts',$posts);

If the other solutions were not working, try this.
如果其他解决方案不起作用，请尝试此操作。
I may think that you just missed this single line "enctype="multipart/form-data"in your form.
See example below:
我可能认为您只是错过了表单中的这一行“enctype="multipart/form-data”。
请参见下面的示例：
<form action="{{ route('upload.files') }}" method="POST" enctype="multipart/form-data">
<input id="fileupload" type="file" name="attachment[]" multiple>
</form>
Don't forget to click the arrow up. I hope I did help you :)
不要忘记单击向上箭头。我希望我对你有帮助:)

not use single quote in $posts
不要在 $posts 中使用单引号
return view('posts.index')->withPosts($posts);
or try second way as
或尝试第二种方式
return view('posts.index', compact('posts'));
回答by Dharmesh Rakholia
You can use compactmethod
你可以使用compact方法
return view('posts.index',compact('posts'));
